If a tank has closed into melee range with your infantry squads hasn't something already gone horribly wrong?
Not sure you have noticed but medium tanks travel faster than infantry.
It was never "originally intended to deal with axis blobs" which is why EVERY MEDIUM+ can crush.. it's just unfortunate that most allied tanks are faster than their axis counter part.
That being said, have you seen what P4's/Panthers can do to allied blobs with blitzkreig?
Fair enough, it wasn't intended but it was a pretty convenient allied anti-blob tool.
Being crushed is not some kind of l2p issue. Crushing of infantry is seen in ESL and top ranked games all the time. Especially Cromwell crush. But I'm glad I offered you another platform on which to wantonly patronise.
Yes I have seen blitzkrieg crush but it's a vet ability, therefore asymmetrical.
